second business paypal but need to delete email from primary business paypal

hi all, i have a business with a specific niche business, now i added a second email for a totally different niche, but when people pay they still see the main brandname which has nothing to do with the 2nd niche business

now can i just delete the specific 2nd email, and open a new paypal on this emailaddress (also with a new bankaccount), or will i get it trouble because the email has already been used for my main paypal account? (it's a business bank account)

thanks
