Lighter/simpler turbo pump

I have been wondering about a turbo pump that consists of a rotary
sprinkler come Catherine wheel physically situated within the combustion
chamber. This should not inhibit regenerative cooling. It is integral,
self cooling, should improve mixing and combustion, requires no
secondary combustion or gas generation and is much much lighter. In
essence it is just a fancy self powering injector.

Thoughts? Has this been done before?

I have worked out a few details on this sort of thing.
Conceptually, kilobar combustion pressures are possible,
which shows that I don't have a firm handle on the theory.
1,500 psi seems possible with hydrogen.

Working on this general type thrust chamber is roughly 219
on my list of 500 things I need to do urgently.

I'm thinking that if used with regenerative cooling it might stir up the boundary layer on the wall and cause it to fail. You'd have to try it.
