> so I am proposing to side-step the restrictions by ordering an Intrepid Camera enlarger
There may be an alternative way to that. Meopta enlargers come into a suitcase and can disassembled easily. You need only a room for that suitcase. I had an Opemus 4 for decades and still have an Opemus 5. That is 6x6. If 35 mm is sufficient you may look for an Axomat which is smaller. Here in Germany it is easy to get one for free.
This is an Axomat suitcase looks like (Axomat III). The ground board is on top, it has been removed:

I recommend this one. The later models need separating the head if stored. Axomat II ( and the similar Opemus 4) are built in a minute and stored in a minute.
