can Hydrosphere/Focused Ballista shotgunning carry an MF meme build?

super super rough PoB (especially considering changes coming): https://pastebin.com/0JRFJ70F

3.16 i'm gonna be making an MFinder just for the fun of it and so am having to build around all of the uniques. it's pretty restricting. there's almost no flat life or resistances on the gear (didn't want to put in some PoB ventors) and so am building around that with a super passive playstyle (bow and ballistas) and lots of jewels on the tree. but also damage itself has been a question for me, especially as i don't really trust my capacity to get an honest readout from PoB with all the moving parts involved.

to work around the damage i'm using ele hit to get lots of flat damage, using an actual bow in place of windripper for more %increased damage, and then pretty much just relying on the sheer amount of projectiles and chaining happening to fill in the gaps.

and that's my question, how much does this fill in the gap? i'm planning just on farming maps with this build and having fun and so generally there's no real pressure on performance. but i'm more than a little optimistic that the HS/FB interaction is broken enough that it will exceed expectations.

would love any feedback or experience people have with this mechanic
