Thanks for the pictures.
The problem with the RHD pedal box is that the opening & mounting point for the brake booster is on the opposite side to the LHD pedal box, right in the way of where the clutch pedal master cylinder should go. I'm not saying its impossible but its going to be a really tight squeeze.
On the positive note, Tozo's custom over-centre spring for the clutch pedal looks like exactly what we need, because there is no way the huge, wide LHD over-centre spring will fit on the RHD pedal box.
Also, the brake pedal spring mounting bracket needs to be cut off and moved to the other side of the brake booster well.
In the picture is a RHD pedal box, with the LHD brake pedal held in place to show where it could potentially be fitted as a clutch pedal. However both the brake pedal and LHD brake pedal bushings would need to be cut down to fit on the remainin space of the pedal shaft.
There is nothing behind the plastic foot rest, plenty of space for the clutch pedal, but no space to rest your foot.
Ideally I would like to keep a smaller version of the foot rest, but that would require bending the gas pedal to the right, reducing the (overly wide) fuse cover, bending the RHD brake pedal to the right and cutting down its rubber mounting plate so the smaller LHD brake pedal rubber pad can be fitted instead, and using a second RHD brake pedal as the clutch. I beleive this could also be possible keeping a small footrest, but with pedal spacings reduced to about 5cm (may be too tight). See last picture for a stiched together picture of the shifted narrowed pedals idea, possibly enough room for small foot rest.

Personally, my plan is to ask Grizz from Unit 20 his opinion how its best to design the pedal box and if he is willing to put it together (I'm no engineer and as IT said I dont want anything to brake, feet can exert a lot of force). I need something else fixing soon so when I get booked in I'll just take all the pedal bits to him and see what he says.
