u can get a L1 L2 and L3 chip of every type, plus a full set of gear bar 1 in ur bank without opening any extra slots.
50 slots in inventory should be more than enough for tokens, stars, cards, plenty of materials and plans,
heck even speakers and still leave room for 6 pieces of gear, especially since u can stack most things to 99.
Leave it as it is, its great timing hits hoping uve won the battle at the last second.
As for switching form, 45secs max, if ur too slow, adapt get faster, or miss the first round, might make u quicker the next day
