I see a saito 1.3 twin on ebay.  I believe it is a gasser.  I did ask over in the glow forum but since you mentioned putting the Magnum in there I thought I may as well ask....how do any of you think the 1.30 twin would be in this model?  Too big?  Overpowered?   I love the idea of a twin and I may be able to win that auction as well.  Ya never know.  But I first need to know if it is an engine to even consider for this model.
