Digital BW, The Print

I have the opportunity to buy an Epson Stylus Pro 4000 printer at a low 
price because one of its color heads is completely clogged. I have 
wondered if this might make a good economical printer for monochrome 
prints larger than I can do with my R2400.

I'm thinking of leaving a cleaning cart connected to the bad (M) head, 
and loading Photo K, Matt K, and various gray carts in the other slots. 
I'd drive it with QuadtoneRIP, and understand I would need to develop 
some custom curves.

Two questions:

1   Is this a crazy idea?

2   What inkset would suit? MIS? Peizography? Paul Roark's 4K+?
