Can't make up my mind!

[Oh How Original]

I can't decide if to order a TF2 or an SCX10, I already have a Yota I body, brand new sat here in it's box.
I'm thinking of a slightly jacked up Yota, which led me to think the SCX10 might be the route to go, for better articulation and slightly taller tyres.
Does anyone know of a cheap route to take to move the motor to the front of an SCX10 chassis though? I'm having trouble finding anything other than the GCM kit, which would blow my budget and make the point of ordering the SCX10 rather moot.
Is there a cheaper alternative, or a 'budget' DIY way of doing it?
I'm unsure if the servo will foul on the motor also, so just looking for advice regarding that too.
My main reason for wanting to move the motor is I'm assuming the bed and/or interior will foul the motor and gearbox in a stock SCX10 platform.
