can one apply in EB1 while her I140 is approved using EB2 category ?

Hello, I have MBA and BE (electronics) from India and 20 years status: H1, got my I-140 cleared by premium processing. Priority date is 2016. Joined this company in US, with them for last 4 years and managing SAP projects in US, Canada, Middle east, Australia and India. Base package <100K but have benefits and annual bonus. My question is: based on my experience can I apply for GC on EB1 category ? If yes will the outcome of EB1 have an effect on my current 140 ?

Thanks in advance.

Any thoughts on the above? Is the forum not very active because of the holiday season ?
