Hi TPott,
I have pretty much the same layout as your original. The difference being I only have 2/3rds of the garage.
Recently i changed the up and over door to a side hinged door , and made the front 1/3rd a "utility room" for freezers, fridges and tumble dryer, with shelving over all these. This freed up some space in the rear 2/3rds as i moved stuff into the utility side.
I have a SCMS on a mobile stand where your Drill is and the Drill is on a mobile stand where your new door is. The P/T is on an Axi mobile base and is pulled into the centre of the workshop when I want to use it (along with a RP DX1000 extractor).
This all works for me.
I do have a table saw (use it quite a bit for 45 degree cuts, cross cut sled cuts etc), I have a RP sabre 350 bandsaw too, mainly used for resawing. I can manage a full sheet of ply (just) and use a tracksaw for breaking this down.
Yes sometimes i could do with more space, but i do regularly use all of the above & as i said - it works for me. As with most of us - your shop will never be finished, you'll always be tweaking it, and then some e.g. Rearrangitis
