If you have a PPL A then hours spent in a Micro do not count to keeping the licence. Have you considered getting a VLA? A lot of the UK micros have “big brothers” which are almost identical versions but with a higher take off weight. For example a Eurostar with an electric fuel pump is a VLA, without it is a micro. Running costs are identical but you can fit more kit and carry more bags.
My MCR01 Club has an extra 40kg useful load over the micro version of the same aircraft! If you have a full licence there are no disadvantages to the VLA route.
