Thank you for your question. If there is an aspect in which your intention for the istekhara has changed you can take another istekhara with that modified intention.
The goal of istikhara, as presented in hadith, is to seek divine wisdom for what path we should take. So, from that angle, the goal of istikhara is not to see how someone's character will be in a marriage.
However, some scholars who have a lot of experience performing istikharas might sometimes be able to offer some insights on the matter, especially if it is glaringly apparent.
It was wrong to do second Istikhara after you have done the first one. Istikhara is one time only for one matter and there is no meaning to second Istikhara unless the matter has changed and became another matter.
