If a virgin woman in heaven can choose a husband of her own choice, can she ask Allah to marry a person who is in a higher level of paradise?
Allah (SWT) The Most Merciful Will grant the believers in Paradise what ever they wish, as we read in Quran (Sura 43, Verse 71) and also in Sura 50, Verse 35.
That does not mean that all the believers in Paradise are in the same degree or rank. Degrees and ranks in Paradise are according to good deeds.
A pious virgin in Paradise will be granted what she wishes according to her degree. Allah's Mercy is over all and it will be more than our imaginations.
Wassalam.
