This is impossible.  A profile can contain at most one package of a
given name.

However, what you can do is create separate profiles:

  guix package -p pytwo -i address@hidden
  guix package -p pythree -i address@hidden

… or use ‘guix environment’:

  guix environment --ad-hoc address@hidden

HTH!
