The higher spec RGs have always had Edge family or fixed Gotoh style bridges. There was a Japanese run or RG621's with a wilkinson bridge in about 96 but these are rare as hens' teeth.
I too would look out for an RT model, preferably an RT 650. These were released in 92 or so and featured Alder RG bodies with Vintage style trems.
The R series guitar was available with a vintage style trem in 1993, the R355 had an R style body with a vintage trem
The SV series of that time took the S style body and had vintage trems and locking tuners.
Alternatively look to brands such as Anderson, Grosh, or Suhr for a Super Strat with more Strat
