David,

Try using a virtual package and combining provides=()  with conflicts=()

example

pkgname="foo"
provides=('foo-base')
confilcts=('foo-base')

pkgname="foo-alternative"
provides=('foo-base')
confilcts=('foo-base')


switching between foo and foo-alternative should then be possible by 
doing a simple pacman -S (or -U) .

Note : it can be done without a virtual package foo-base, but imo using 
a virtual package makes it clearer what happens, especially if you want 
to test multiple alternatives.
