I didn't know you cared was a similar vein and the last stab was Boomers with 6 mature actors including Hobbo and it was picking up viewers when Auntie binned it
but for me I think compatible scenery i would have it set in Scotland and cast wise I'd have Gregor Fisher and Elaine C Smith as a complete reversal of Rab C and Mary Doll as laird and lady of a castle. Tony Roper [Jamsie] and Barbara Rafferty would assume similar roles to those in Rab but with twist they come into money from a lottery win and it becomes a one upmanship contest between the pairs after Tony and Barbara's acquire a nearby stately home which they tastelessly decorate in a style of people who are not born to that lifestyle .
You could filter in some uppercrust characters for example a butler and have two actors playing it straight with one devoted to the laird and lady and clearly looking down on the new wealthy couple , they themselves have a straight laced butler who treats Tony and his wife with disdain out of site but is sycophantic when it their company .
It is very off the cuff first thoughts but it is something I think could work .
