First off you will have to pick a theme/army type.
Descent of Angel; Aka jetpack assault marine spam, usually has Dante and some Sang guard, some sang priests and maybe a drop-podding dread or missile devastators. Your models cannot support this list.
Mech Spam; Razorbacks, predators, dreads, vindicators...etc. Couple of sang priests in the razors with assault marines w/o jetpacks, led by a librarian. Basically a heavy shooting army with some combat teeth. You cannot support this army, not enough vehicles.
AV13 Wall; Baal and normal preds as far as the eye can see. You cannot support this list.
All that leaves you is the not very impressive "mis-mash" list. I'm in a similar boat. I have a 3000ish point vanilla marine army I'm converting over to a
BA force, but contrary to what you might think, there is not a ton of over-lap between Vanilla and
BA effective units.
Was this a fourth edition marine army? Cause plasma sucks now, FAR too overpriced. Feels very battle-force-ish.

Captain with Power Sword/Combi Flamer
Chaplain with Jump Pack, Crozius, Bolt Pistol
Chaplain with Terminator Armor and Storm Bolter
Librarian with Force Weapon(missing his left arm)
Captain is junk, doubly so for
BA
Chaplains; are second rate to...
Librarians; rock, and this will have to be your commander. Jetpack if you decide on
DoA. In a razor if you go mech or AV13 spam.
Techmarine with Bolt Pistol, Power Sword, and Servo Arm(He's my good luck charm)
9 Tactical Terminators, 2 with Chainfists. No heavy weapons.
3 Assault Terminators with Lightning Claws
Can't fill out an assault squad, and no
LR or SR to deploy them make them unimpressive. Tactical termies suck even in this book especially w/o cyclone to give them some teeth.
Techmarines ALWAYS suck.
1 Dreadnought with Assault Cannon and Power Fist/Heavy Flamer
1 Dreadnought with Multi Melta and Missile Launcher
Dreads are heavy support for
BA, so remember that. Ass cannon and hvy flamer isn't too bad, but I question the
MM/
ML dread.
Sixteen Tactical Marines with Bolters
Two with Flamers
Two with Missile Launchers
One with Plasma
Two Sergeants with Plasma Pistols
BA really should not be using Tactical marines....ever. Some of these models are at least usable at least.
Seven Assault Marines with Bolt Pistol and Chainsword
Two with Plasma Pistols
One with Plasma Pistol/Power Sword(Sarge)
Meh. Plasma pistols need to be swapped for melta-guns or inferno pistols. Serg needs to lose his power sword for a fist probably.
Ten Scouts, all with Combat Blades and Bolt Pistols
No point to these really, too slow on foot.
One Predator with either Autocannon or TL Las, HB or Las(Magnets, how do they work?)
One Razorback with either HB or Las
One Rhino
One Whirlwind
Whirlwinds stink, but at least we have some armor here.
One Apothecary
One Standard Bearer with Plasma Pistol
One Company Champion with Combat Shield and Power Sword
One Veteran with Power Fist and Meltabombs
Interesting. Apothecary will be used for sure, the rest is mostly junk, but I'll see what I can do.
Now for a mish-mash list with what you have available.
~100 Librarian, no toys, 2 powers of your choice. I'd suggest Shield and Rage, or Shield and Lance
~250 Honor Guard, jam as many melta or flamers as you have in this squad, your apothecary and throw them in your
TL-
LC razor back.
~250 10 Assualt marines, 2 inferno pistols, sergeant with inferno pistol and powersword. Inferno pistols are over priced and should be melta-guns really.
~240 10 Tactical marines, plasma-gun, missile launcher, combi-weapon on the sergeant (easy to convert one), rhino. Crap choice for
BA and should be replaced with more ASM ASAP.
~135
AC/
LC Predator
~110
MM/
ML Dread
~125 Asscan/Hvy flamer dread
That's...as far as i can go without getting into third rate choices. You could round out a 1500 point list with 6 shooty terminators with a cyclone missile launcher and a few other toys here and there I suppose, but this will not be a first rate army by any stretch. I'd give it like a 4 outa 10 in terms of competitiveness. Better then a crap battleforce list, but not by much.
