No offense, but Maria Antonia's father was a bit of a dick about her succession rights to Spain OTL (having her sign a renunciation thereof on her marriage, and then AGAIN in favor of her infant son), both of which Carlos II considered invalid - which was why he nominated her son (perhaps out of spite?) instead of Anjou or the Archduke Charles. (And granted, it was also probably under pressure from his mama, the queen-dowager). Another thing, Leopold was promising the Spanish Netherlands to Max IF Antonia renounced her claim (which naturally Carlos was furious over, since he regarded the Netherlands as belonging to him) to the Spanish crowns (either in favor of her father (originally), then her half-brothers (when the marriage contract renunciation was signed) and finally her son (naming Leopold or an Austrian archduke as Regent (instead of her husband) (the second renunciation)).
That said, Antonia's marriage with the elector was apparently rather tempestuous - she was aware of her status as the heiress to Spain, and she never let her husband forget it, and he was ambitious and scheming. While there were periods of happiness, the six pregnancies (usually the three miscarriages she had in 1687, 1688 and 1691 go undocumented) didn't help her nerves any. However, they shared a love of music and theatre (inherited from her parents).
So, to my mind, whichever husband she marries, she's going to still have the same personality (possibly) knowing that she's the heiress to the Spanish dominions, and ergo, being puffed up about it. This would lead to friction with any husband in a time when women were regarded as inferior/subservient to their fathers/husbands.
However, it does make for interesting speculation. Although it is a valid point to remember that her OWN grandmother, Mariana of Austria, when the time for Carlos II to marry in '79, didn't want her as a daughter-in-law due to the reports she had heard about her temper and behaviour (I think Antonia marrying Carlos might've been an earlier version of Maria Anna of Neuberg IMHO) but also because Carlos would have to wait at least three years, and nobody was sure that the king would have that long.
That said, one of the Ferdinands daughter's could maybe hook Carlos as a bride (she'd be comparatively unrelated (much like the Neuburg lady), and if she favors her Gonzaga looks rather than her Habsburg, beautiful, too (something that all of Eleonora Maddalena Gonzaga's daughters were reportedly).
