Wouldn't it still be illegal to make 4 or more daytrades within 5 business days in different accounts?

First of all, it's not illegal. It's an NASD rule, not a law.
One brokerage firm has no knowledge of another's activities. This is a brokerage firm rule, not a rule for individual traders. You could do 3 day trades in 3 (or as many as you want) different accounts, as long as you don't violate the rule in an 1 of the accounts.
