Is any one looking to build a bigger MR1 with more X

Hi guys i have one of the first mr1 mill’s and i am looking to buy one more to do mods to it in the X only .
I am happy with the one i have BUT there are some things i need to do for the drag bike parts that will not work .
I will use all the part from the mr1 base unit parts .
what do you think

If starting from scratch, I would think adding more Y would be easier mod, just need longer flat bar, linerar rail, and screw.

a longer x gantry would be a lot more work.
