I’ll leave it to others to answer the rest (I don’t know the answers to those), but the answer to this is clearly “no”. Otherwise, a user writing a series of Emoji in prose would find that any attempt to space them using the ordinary space character led to unexpected behaviour.

Also, I don’t think you can rely on spaces undergoing glyph mapping; because renderers need to handle spaces specially (for justification and line breaking purposes), it’s quite likely that at least some renderers special case them.  It’d be interesting to see what various popular applications do if you try to make spaces change size using OpenType...

Kind regards,
