I went through a similar thought process last winter when I rescued a dual axis 1.8m Prodelin. The technical solutions were fairly straightforward. I would have used two GBOXes for the azimuth and elevation actuators, but would have run them via computer control and a DiSEqC switch. With regard to skew, I had no interest in polarotors because of their crippled performance. Instead I considered getting a single mode motorized feed for adjusting skew, but that is quite expensive. All-in-all it sounded like a lot of fun, but not worth the time and money to me.
I found a rusted, junker Ajax HH motor, refurbished it and converted the reflector mount into a polar mount. It wasn't hard at all and only cost about $60.
