H1B transfer while wife's I-539 (H1 to H4) change of status in pending

[Don'tAbuseH1B]

Here is my situation,

Currently, I am working with Employer A on H1B visa, Today I got an offer from Employer B, Wanted to transfer my H1B to Employer B.

My wife was on H1B in 2020, stopped working due to some issues. we filed I -539 Extend/Change Nonimmigrant Status ( from H1 to H4) in Sep 2020, which is pending status. (waiting for the biometric appointment.)

Question 1: Is this a good time to transfer my H1B to the new employer (B) while my wife I 539 is pending? will my transfer affect my wife I -539 petition?
Question 2: I have discussed my situation with Employer B they are not willing to file H4 along with my H1B because my wife I 539 change of status ( H1 to H4) is still pending.
Question 3: What are my options if I choose H1B transfer with Employer B without H4 filing.

Please advise,

Thank you in advance.
