Strictly, you don't need any instruments - ya missed the word
"standard!" 91.205 applies only to aircraft with a standard
airworthiness cert, which does not include experimental. However, AC
20-27E which certifies exp's sez FAA "may require" the instruments
required by 91.205. You can bet they will, as you simply won't be
able to comply with certain Part 91 flight rules without the 3 you
listed.
They could theoretically balk at electronic-only flight instruments,
since they have to rule on "airworthiness" in general, and can pull
out any old document to define that; several I'm thinking of flunk the
uEncoder w/o approved backup. FAA up to now might not have done that
often, but they are moving toward using all DAR's for sign-offs. These
guys will likely have legal liability that the gov't does not, and how
that colors their judgment has yet to be seen. Leave some room, so you
can add anything the DAR insists be there, like at least a mechanical
ASI?
