This is the problem with putting a 50mm lens on a turret, it may not be able to be moved out far enough so the turret can rotate, w/o affecting its ability to focus when the head is elevated to the top.
The film/lens setup that I am planning for is:
35mm = 50mm lens
6x6 = 80mm lens
6x7 and 6x9 = 100 or 105mm lens
4x5 = 135mm lens
The reference to the XL chassis is the Extra Long girder/column, compared to the standard length girder on the Omega D5 enlarger. The XL chassis with the longer column would be able to print a larger image on the baseboard. The problem is I do not have the vertical clearance in my short "basement" to install and use an XL chassis. I would have to have the baseboard down on the floor, or no more than 1 foot above the floor, to fit.
That is why I finally decided to use a 135mm lens for 4x5 rather than a 150mm lens on the Omega D5.
BTW, re the reference to a L1000. I am currently rehabilitating a Durst Laborator 1000. What that really means is that I am gathering the missing parts for it to get it fully operational. And as expected for a Durst, parts are hard/virtually impossible to find, so I am being pushed to fabrication to replace some of the missing parts.
