Yes. Doing this while retaining the air conditioning will be tough as this will require a belt driven oil pump that likely needs to be clogged off the crank pulley. Installation will be much easier than a 3 stage dry sump (2 scavenge and 1 pressure stage) however as it's all done externally. It would be no more difficult than adding an oil cooler and pulling the AC pump.
Also, what about separating the oil channels, having the external pump go to the mains and have the OEM pump cover the top end, or vice-a-versa?

It's easier to block the internal feed to the mains and supply oil via the external galley plug. Really though why bother if you will have to bolt an external pump on anyway.
This is where we stand right now as for Element Tuning we need to discover issues and then come up with staged solutions for our engine and Hydra customers. I have a couple more tricks up my sleeve that I need to test but I do think a good air to oil intercooler is going to be a must for turbocharged setups in the 400+ hp range. The cooler oil temps will overcome the pressure drop from the added restrictions.
If my "trick" doesn't work then I do believe an external oil pump along with the oil cooler would be the next stage. Track day boosted people could add an Accusump and some sort of large drain back air/oil separator.
Racers on built motors, turbocharged, slicks, and downforce like us will just need to go to a 3 stage dry sump which is a $5k investment. I'm hoping I can figure something out so we can get away with a 2 Stage like we do with our STi so a dry sump is $2k less.
