Sounds good but you might have problems with pollination as many apples
need
another variety (Or 2 in some cases) to pollinate them, and they have to
be
in flower at the same time.

'Fit in fruit'
M27 rootstock frows to about 6ft/2m high.
Self fertile varieties - Queen cox self fertile, Red devil, red windsor,
saturn, red falstaff.

Conventional varieties Bramleys seedling, James Grieve, Ashmeads Kernel.
Need one or two pollinators, depending on variety, which is why I said you
get three varieties on one rootstock earlier.

M27 needs staking and grows in a tub.

M9 is another dwarfuing rootstock 5ft/1.5m high

5lb/2.5Kg of fruit per season is reasonable.

Columns, step overs and espaliers are also mentioned as good ways to get a
lot of fruit from a little space.
