No...not for the faint of heart...but not impossible.
Think of a 37-620 or 37-630 chassis, which is jam-packed enough...then add another output tube, more parts, and you have a 37-640. The chassis is even the same size as a 37-610, 37-620 or 37-630...which is why it will fit inside the Bullet cabinet.
Does that induce nightmares yet?
So anyway...
When I work on a Philco with an RF unit, I like to make a diagram of the wires coming from the RF unit and connecting to various points in the main chassis.
Here's the one I made for this 37-640 (click to enlarge):
