Default Foam Block To Bass Boat... can this be done?

Hello

I have a wacky idea, some time, space, and a little cash; plus a buddy
that just bough a really nice bass boat. See I want a really nice boat
like this too, but I'm broke and or cheap, you'll have to ask my
wife...

I'm thinking I can measure and trace every inch of my friends boat and
can carve a duplicate of the hull from one full piece of foam creating
a core for a FG bass boat of my own. Hull and top side front and rear
decks, plus cockpit along with carving out all of the storage nocks
and crannies. Then also carving in small recesses the length of the
keel, shear line, and in a cross hatch on the transom. Possibly also
some following the line that battens would run.

Once the core is carved starting to lay up glass using the keel, shear
line, transom and batten recesses in the foam to form thicker members
in place of stations (could be way off on the usage of that term),
then doing a final allover application to encapsulate the hull bottom,
sides, deck and cockpit with the foam in place.

And assuming this can be done

Question time:
Is this sufficient strength for a boat of 16ft with 50 to 60 hp?

Is this limited to closed cell foam construction only; is it possible
to use other foam types?

Could joined pieces of foam be used or is a sold piece preferred, and
what would be the best bonding agent to use to build up from multiple
pieces?

Could A / B mixture expanding foam be used?

If carving an A / B foam mixture plug as opposed to solid stock,
should the weight be 2# or 8#, is there a denser product?

What types or weights of glass tape, mat, or woven roving would be
used to get the best results?

I know these might sound like the oddest questions but I would really
love to know if I can do this. I’ve been dying for a boat like this
all my life but the dog would get braces before my other half would
let me pop for one at a dealer new or used. This way I’m just being
eclectic and might sneak it past her until it comes time to build or
buy a trailer and go fishing!
