Off-boom sheeting

I'd guess the boat originally had a swivel block and cleat behind the traveller. Modern 420's seem to favour strops, maybe you could convert to that and use the traveller fixings on the CB case for the block and cleat?

Hold the tiller extension across your chest and you can hold both with one hand plus the added advantage of being able to sheet in hand over hand. I can't think of any advantage* to an aft mainsheet, I hated it in my Heron when I was 12/13 and tolerated it in the Ent in my 30s but, for me, a centre led mainsheet is better in every way.

Never sailed a 420 but I recommend looking at what the top 420s have and replicating their system. Copying is the quickest way to get better.

Love aft sheeting. Grew up with it. It leaves more space in a boat to move around, means you don't have to move aft tacking in light winds, and give far better purchase. Less control gybing in a breeze, though.
Off boom seems to work for some boats and not others. All to do with ergonomics, I guess. For instance, in a Minisail, it makes sense if sitting on a sliding seat, but not if lower down on the side deck in the standard boat.
