Does it really need a pump if it was designed to run without, but I noticed that you mentioned its slightly modified?
The reason I ask is my dads got a Riley and a Jowett which both use thermosyphon and they warm up quickly and don't boil.
If you're worried about it taking too long to warm up I would at least measure the oil temp before ditching the cooler, you can get oil stats as well...
