Avy-J has no genoa track, and I do not intend to fit one. The genoa sheets are led to the winches via blocks shackled onto the toerail.

The genoa is a fairly high-cut yankee, so the lead is not too bad with one or two reefs rolled in, but obviously any more than that and I would like to move the sheet lead forward.

(With minimum faff)

Three possible solutions I have come up with are:

A) Snatch blocks forward of the existing blocks (eg Antal 56). Snap in sheet, it still runs through the aft block for a good lead to the winch.

B) as above, but use low friction snap shackle instead with a plain pulley
Seldén Low Friction Snap Shackle €48.94

C) have a 'floating' standard low friction ring on the line, and barber-haul it down when I need to move the lead forward.

B) and C) both allow more variation of lead angle, but C) might cause problems - could tension be maintained with a bit of bungee cord?

Google 3D leads. Simpler, more flexible, no need to reinvent the wheel. Many variations.

LFR, option C
Go for the lowest cost. LFR are very useful for your issue. You can buy ones with a buffer material on the edge to stop them clattering, tapping on the deck, if that is a risk.
 
I know nothing, but it seems to me that (C) offers the possibility of making your adjustment without leaving the cockpit, and since I am afraid of falling in the water, this seems to be a good thing.

Plus a LFR seems more minimal, and probably cheaper, so less is both more, and ...er...less.
 
On my last boat, also with no cars I did C (with a block as lfr weren’t a thing). It was very good indeed.

I took a great deal of pleasure in adjusting the hauler though a 4:1(?) block to get the perfect sail trim. What’s more the windvane would keep it perfect as if the tell tails were painted on the sail.

Would happily do it again and I would argue it’s a better system than my current boat with cars with pins which are a pain to adjust in comparison
 
OK you have a block situated to sheet the full genoa. (set block. Green)
You need something to properly sheet a furled/reefed genoa.
How about a frictionless ring fitted with a soft shackle that is floating between the set block and the clew?
Or even two?
Of course this is set up on both sides.
In the illustration the Light green is the set block and the blue is the floating (fitted but not set) frictionless ring.

You could set up a tweaker with a low friction ring for the sheet lead back to the cockpit via a block on the toenail reasonably well forward of the existing one. By pulling down on the tweaker you can vary the lead as you reef the genoa

So does A if you have a meter or so of line attached to it.

A snatch block on a metre of free rope can smash cabin windows, shins etc. Seen a window smashed in fairly gentle conditions when sail flogged. LFR much lighter and hence less dangerous, especially if a thickish attachment rope right round it.

PS. Surely the OP will need some form of adjustment even when not furled. It is extremely rare that the sheet lead for a beat is the same as for a reach or downwind. We adjust the jib cars as soon as bear off. LFR would help here also
