Chainline question, re. using an mtb triple as a wide range double

So I have a nice old set of 94 bcd Sugino XD triple cranks that i want to use for a wide range, 46-29 double. The thing is, because they are meant for mtb use the chainline (measuring to in between the outer and middle ring) with a 110mm bb is out at 49mm. If I use a 102mm bb from velo orange, basically the shortest possible, I can get the chainline down to 45, which puts the outer ring at around 49 mm.

Will having my big ring that far outboard potentially cause any problems? Ideally with a wide range double setup you want to be able to use most/all of your cassette from the big ring, and my worry is that with this chainline that's not really going to work out.

So, has anyone tried a setup like this? what can i expect if i go ahead with it?
