If you can cut every few days in the growing season then leaving the small
clipping in the lawn is a solution.
I would treat the moss as a seperate problem - but then spiking and dressing
half an acre of lawn is as daunting as cutting it every few days.
I think you can hire motorised mechanical thingies which will ventilate your
lawn by lifting out small cores of soil, and this may be a realistic option
for a large lawn.
It could be that one push to improve your lawn by removing the conditions
which encourage moss would then enable you to mulch the clippings back in
for the rest of the year without problems.

Yes I know I can compost them, and I do to some extent, but I have
almost half an acre of formal lawn and only have a few places I can
use the compost, I give much of it away but even so there is just too
much volume of cuttings and the compost bins are full.

The lawn is prone to moss so I know I should pick up the cuttings
instead of mulching back in, (I use a cylinder mower) at the moment I
take them to the tip but there must be a better solution !
