Some of those points are pretty wacky. 190pts for a deepstriking conqueror is not worth it. Swap that with the desiccator tank (that one should be 190).
Also, you mean sponson upgrades, not pintle. Pintle mounts are on the top hatch. Sponsons are the side guns.
Adding to the list though, here's one I came up with a while ago:
Invader Heavy Infantry Tank (russ hull, no turret)
100pts,
AV 14/13/10 Tank, Heavy
3 Heavy Bolters (hull, sponsons)
Swap Hull
HB to H-Flamer, free
Upgrade Hull
HB to Lascannon +15 points
Swap sponsons for H-Flamers, free
Upgrade sponsons to Autocannons +20 points
Upgrade sponsons to Lascannons +30 points
Buy one squadron of 1-3 tanks as part of an infantry platoon.
I just want a bunch of these rolling up with my guardsmen.
