No.
If you build a network of satellite sites to support your main site, this is always a difficult thing. Google is able to detect those connections in various ways (the most easiest way is to sum them all up in one GA account!).
Even if you would use separate GA accounts this would not prevent Google from detecting your connections.
If you overdo that you will get no positive effect and the risk to get a penalty will rise.
E.g. if you use 5 sites to support your main site this might be ok, but if you build up 30 sites Google will recognize that as not trustworthy.
There are several ways to avoid that - for example to use different IP classes from different networks. This can be done if you use different registrars for your websites BUT if Google wants to find out about that, Google will be successful. If you become suspicious they will check the whois and if the data is always the same... BANG
Never, never use anonymous registration. Those sites always have serious trouble.
So please be careful with your network! It`s a lot of work and time with lots of snares.
But to answer your question: it won`t help you if you use different GA accounts.
