Before you carve out the holes you could mock up with just the lower bolt installed and then pack out the strut to knuckle with something of appropriate thickness to see what sort of result is possible. 

I'd also be looking at something such as an oval washer or space to make sure the bolt can't shift in the slotted hole as it'll be under a fair bit of load at the track.

Yeh good idea, il look at some of the asymetrical adjustment type bolt's, like this - https://www.redlineperformance.co.nz/product/bc-adjustable-suspension-camber-bolt-kit-14mm/?srsltid=AfmBOor42f2GxhGrR8Yr-TMmj4olcaXzOYdjYmc1SU-Ny2NCmkvZt_g0

Would be nice to get the camber back to neutral and have that reflected on the top plate aswell...

Yeah depending on wheel width offset etc a bit of slotting at the knuckle connection could very quickly eat up tyre  to strut clearance. Best to figure this out during a mock-up.

I'd be looking for something preetty foolproof for a locking mechanism as it's not quite loaded like a standard suspension bush eccentric bolt.

Something similar to these serrated washers and tabs to be confident it can't shift. Then do your fine tuning back at the top off the strut.

The simplest cheapest (free)option would be to weld up the portion of the strut hole that's nolonger used.
