Doable, IF you keep it really light...and you'll have to move the wing tube forward about 3/8".

I wouldn't suggest it personally. That engine is a brick, and not sure it puts out enough power to make it worth the extra weight.

Pumps: I'm sure there's a way, but I'm not aware of the specifics. I know there's a way to pump a Saito, so there has to be a way to pump the magnum. But how the magnum reacts to it, that's anybody's guess if you haven't tried it.

I dunno, doable but...worth it?
