H1B Transfer in parallel to H1B Extension

[H1B_User_Bpl]

My current H1B Approval notice is valid till March 31st and my I94 is valid till April 10th.

My current employer A is planning to file my H1B extension close to March 31st, around March 28th or 29th.

Employer B is planning to transfer H1B at around 25th March.

Question -  If my receipt notice from employer B comes after March 31st (say around April 5th), can I continue working with employer A for 2 more weeks i.e. give a notice of 2 weeks and then join employer B at around 22nd April? As I am leaving employer A, I am assuming they will revoke my H1-B extension once I leave. So my working with employer A till Aprill 22nd would be allowed in that case? What other options do I have. 

Please suggest.

Yes. But if the receipt from B comes after April,10, your H1 petition with B may be approved without an I94 unless the existing extension from A is approved. Of course if the receipt comes in before your I94 expires, you can go ahead.
