You need a wider chainline anyway on an MTB than you will achieve with an external type road crankset.
The next issue you will face is getting a road derailleur to adjust out to work with a 50mm chainline. Some might do it, and some might not.
Thanks for the reply.
I was planning to use SRAM mtb 10 speed rear derailleur with SRAM road shifters.
Something similar to this

Pretty much the only thing I need to figure out is the crank/bb and the FD. I can also use SRAMs 10 speed MTB crank/FD however that would add an additional cost to my project as I already have Ultegra and Rival road cranks available.
