Jim,
I suggest that you have better antenna efficiency alternatives than the
hamsticks.
Since you have a 33 foot mast - I assume non-conductive - I would
support a 32 foot wire from the top of it for 40 meters. Add one or
more 32 foot counterpoise wires (radials) along the ground.
Then for 20 meters, haul a 32 foot dipole on the mast (fed at the
center). That will serve as a vertical dipole and should work fine - no
radials needed.
Cost is only wire and the coax to run to the feedpoint. Since you will
likely have a short coax run, you can use RG-58 with little loss.
Your ideas are quite workable, but if you have the 32 foot mast already,
why spend the extra $$$ for the commercial antennas - just invest in
some wire and have fun.
I might add that you can also use a 58 foot radiator (supported from
your 32 foot mast) in an "inverted L" configuration with a 13 foot
counterpoise on the ground. No feedline, just connect to a BNC to
binding post adapter and the KX2 internal tuner will handle it just fine.
Those lengths were recommended by one of the KX2 Field testers who does
a lot of SOTA activation.

Waiting for my KX2. Plan to use for camping and stationary mobile.
Initially, the antenna for stationary mobile will be hamsticks (40 & 20m)
mounted
to roof rail on suv.
Thinking about trying a 16-17' mfj whip on the roof rail mount. Should be a
1/4 wave on 20m.
With a couple of wire radials it should work better than a hamstick. I expect
the KX2 ATU should
"Tune" it on 40 and maybe also work better than the hamstick.
Has anybody used one of the mfj whips with a KX2 or KX3?
BTW, for camping have a number of antenna options: endfed wires, dipoles,
verticals supported from trees or 33' mast bungeed to the awning of travel
trailer. Nothing beats camping and playing radio...
