I am not sure I understand the issue with having a timeshare ownership secured by a deed, versus membership in a travel club that secures your interest in a trust, but there is already a Wyndham-based product that provides what you're looking for - Club Wyndham Access (CWA). Points associated to CWA contracts spend exactly like points associated to a deeded timeshare. The only difference is that you have Advanced Reservation Priority (ARP) at ALL resort locations that participate in CWA, versus specific ARP at a single resort.
Myrtle Beach is a key area where owning CWA can make a lot of sense, because CWA maintenance fees are "average" where most of the Myrtle Beach resorts have above average maintenance fee rates. However, you do need to be aware that CWA only has a percentage of the units available in inventory at each resort - in some cases and during certain seasons - a very small percentage. So while if you own at Ocean Boulevard, you'd have access to all of the Myrtle Beach inventory including Seawatch, Towers on the Grove, Westwinds, Cottages, and of course all 4 Towers at OB; with CWA you'd have ARP access to only the CWA portion of those resorts during that timeframe.
CWA is ownership in a trust that owns at approximately 70 Wyndham resorts. As such, you have less exposure to Special Assessments (more likely to have a portion of an SA; less likely for it to be material since it's spread across the entire portfolio of holdings); you have an "average" MF that is more stable than MF's at a single resort (particularly an oceanfront resort); and of course the ARP rights at many resorts.
Most CWA resale contracts are running around half a penny a point. Sometimes you can catch one cheaper than that. That would probably be your best bet.
