Converting Broadway Y6b to Y6a ... how easy?

[NW Modeling List]

I started a conversion of a BLI Y6b into a Y6a a few months ago. I haven't
finished all the little details, but I did go ahead and paint it. I cut the
smoke box down with a cut off wheel on a dremel tool and rejoined it to the
boiler. The down side is I ran out of room for the smoke unit to fit
inside, so it got left out. I cut the catwalks and moved them around, moved
the air compressor, mounted the feedwater heater and ran some piping to and
from it. I practiced on an old rivarossi y6b first before sacrificing an
expensive BLI. There's more I want to do to it, but for now, I'm happy with
it.
