Buying HGVC

Considering buying a HGVC property. Would like info on how this would merge with my existing Club membership.

With all due respect, this is not a question that you should expect RedWeek personnel to be able to answer. RedWeek actually has NO affiliation with HGVC. I'd suggest contacting HGVC directly and / or posing your question over in the HGVC-specific forum on the Timeshare Users Group site, where there are many other HGVC owners who might have direct personal experience with your particular HGVC question / issue.
