Buy a back-up. Set it on the shelf.
Crash this one until it leaks.

To what end?
It's going to take a few applications, considering the depth.
It's not going to make it crash any better next time.
Body filler isn't really made to fill something like that... It's made to smooth out small imperfections. This is more than a small imperfection.
If you were to pound the dent out and then there were some places that needed a few 16th" to look nice, then yeah, but just filling the dent with filler isn't advisable. In a "mass" like that it's likely to expand / contract different than the tank, and will probably crack and fall out anyway, looking even more crappy.
I wonder if it is worth trying to pry some of those out with a pry bar passed through the tank opening.
Possible. Some of the creases are fairly sharp. The problem with trying to remove the dent is that you *may* tear the metal where it has already been cold worked.
The sharper the crease the higher the risk. Heat can help reduce the risk of tearing, but now you're trying to work a hot tank, which adds other types of difficulty :-).
Just be sure and set up a camera first.
I *think* carsick has a fire extinguisher handy.
From prior experience.. it wont be easy. A MC tank is THICK for the reason shown in the photos. You'll have to go in through the bottom ( Fuel pump area ) and use a dull piece of hardwood and a BFH.... Or the same process from the top if you can get to the dents easy. OR go to a bodyshop and have them zap on some of those spines you can attach a slidehammer to. It wont be pretty, just less dented.
Maybe I should ask this guy for some tips:
