Quick home electric question

i think i got this sorted out

plan A
move the meter to the 200 panel box, and install an interlock like this one

plan B (only if i cant move the meter)

install the generator on the 100 amp panel
replace the breakers marked 4-5 with these

and attach the circuits that are now wired into 2-5 on those 4 new breakers
that frees up spots 2-3
move down 30 am circuit 1 into spots 2-3
that frees up spot 1
install new 30 amp breaker in spot 1, hook up generator and install mechanical interlock

this will place my generator on the north side of the house, which i dont like, but i might be able to move it to the northern corner of the west patio, where it is still outside but under a roof and out of the elements
more importantly, both plan A and plan B include a interlock switch and are safe, correct?
