Then fit some form of adjuster under each corner utilising the four screw holes somehow to give us some sort of manual bed-levelling or would that not work? Kind of a fine adjuster setup. The corner clips would have to be adhered to the glass. Ideally removable. The fine adjusters would then be able to raise and lower the bed just enough to fine tune it. What do you guys think? Is it doable?
Sounds totally doable. I've had similar thoughts (though your idea for re-using the stock clips is a new one) that involve printing little nut trap inserts to fit under the bed. There are some parts similar to this all over Thingiverse but it can be hard to find just the right one to fit a given situation.
That said, I'm currently planning a total overhaul of my Y axis anyway, which will involve putting together a new bed support. I'm going to use printed V-slot and rail clamps to support two 8x600mm rails, then more V-slot and printed bearing holders for the carriage. I haven't yet figured out how I'll mount the bed itself, but I'm thinking I'll insert some kind of adjustable platform like you're talking about, maybe using something similar to these (though I'd like to find a design or adjust this one to eliminate the springs): http://www.thingiverse.com/thing:1320658
For mounting the clips upside down on the bed, I'd probably go for mounting tape. It's a flexible (foamy kind of) double-sided tape that should be easy to find at big-box hardware stores. Very sticky stuff.
