I think what you have to do is convince people to spam foot fire warriors and
IG heavy weapons platoons. Then assault marines would clean up.
I think it's important when discussing homebrew rules to identify whether you're designing around highly competitive environments or more casual ones. In my meta, bikers, centurions, wraith knights, and jetbikes pretty much only show up at tournaments. Wraiths and riptides are a bit more common, but still a pretty rare sight. So designing assault marines (or any other unit) to be on park with things like scat bikes would actually mean they'd been made too powerful to enjoy in my local meta. This is especially important when discussing homebrew rules as such rules really need your opponent's thumbs up if they're going to see the table. I mean for this to come across completely politely with the intention of pointing out an alternative perspective as you seem to be pointing out that certain units are notoriously powerful and suggesting that any unit being homebrewed needs to live up to their standards. I may be misreading you.
+1 strength, shred, and rending seem a bit busy to me.
Ap 6 with any one of those other rules would be reasonable, I think. Personally, I kind of like the idea of bolt and melee weapon having slightly different profiles based on your chapter. Ravenguard might get a heavy 1 sniper shot for their bolters and rending on their melee weapons (go for the weak points!) for instance. That's probably a bit busy of an idea and off-topic besides though.
Something I've pondered is giving jump infantry (or at least assault marines) the ability to jink. If a bike can move quickly and wildly enough to get a cover save while still stuck on the ground, surely a slightly smaller target moving in three dimensions is at least as difficult to hit, right? Plus, assault marines give up less fire power than bikes while still leveraging superior (sans the toughness difference) melee potential. This would mean that jump packs would jink "better" than bikes and have the ability to deepstrike, which might make them slightly more appealing next to their tougher, pricier cousins.
Also, captains with jump packs should really make assault marines with jump packs troops or at least allow them to fill compulsory slots somehow.
