It might be fine to do just that. I'll take a look when the pan is off.

The oil feed for the pump is at the lowest part of the pan, so it shouldn't be affected. However, the counterweights are also extremely low in the pan, meaning removing them will cause oil levels to drop. Anything which relies on lubrication from oil in the sump will no longer have oil.

It probably goes without saying but I also wouldn't be able to read the oil levels with the factory dipstick, or possibly any dipstick.
