What to pick for 2.9k spark plugs in R&D?

I was gifted the R&D BP, but I lost my laptop and was forced to take a 1 month.

I currently have 2820 spark plugs, and with about 19 days left on the pass, I think i can get another 2 levels, which is 80 spark plugs, making it a total of 2900 (and maybe 3000 if I didn’t miss out the league rewards for those 2 more weeks).

With just short of 3000 spark plugs, a 2nd Legendary cabin is basically impossible. The best i should do is to pick 2 fused epics.

what on the fused epic weapon/modules on the list should I pick? After all, not all of them are god-fused (like Equalizers and fidgets, those 2 still need spread reduction more than projectile speed), and I believe my current expected spark plugs can only exchange 2 fused epic parts.
