I still believe that you have no need to be concerned.
The deep sump should have a modified pickup to go with it, to provide all of it's added oil benefits, but the difference is about 1/2 of an inch.
I could get you a pickup that goes with the deep sump if you'd like to change it. I have photos that I could share of an improved pickup that I made as per a friend's design.

Wow, this group is certainly experienced with dumping oil out of live
engines! I understand it was common practice to do hot engine oil
changes on irrigation engines. It was to cumbersome to take the engine's
completely out of service which would require re-priming to get the
pumps running again; instead, they brought the engines to a slow idle,
opened a ball valve to drain the sump, spun on a new filter, and
refilled the sump, then the engine was cranked up to full load.
I had my self pretty much convinced that even though I dumped three
quarts out the gauge orifice I never starved the bearings of oil flow.
Now I'm not so sure. I have an aluminum sump which holds 7 quarts. I
pumped out three, so now the question is, how deep does the oil pump
suction inlet go into the sump pan? IOWs, did the oil geyser stop
because I shut down the engine or did it stop because the oil pump
started sucking air after pumping three quarts?
