Double gantry idea, What do you guys think?

Other than that then I wouldn't bother and sell the whole thing and build a far stronger machine from scratch.

when you factor in that my machine will be all steel built, have supported rails, the right steppers/psu as advised via this forum a cutting area of around 500x550 with a 2.2kw spindle and it's going to cost under 1k i'd say it's very likely you would certainly do well to follow deans advice.
