I would say the original conversion of 1000gn = 1wp is pretty good for determining where a PC is in the wealth tiers. Instead of having PC's go through their possessions and add up what each item is worth, I propose simply giving them +1wp per tier to account for the value of their current possessions. So
1wp at absolute poverty
2wp at destitute
3wp at struggling
4wp at poor
5wp at average
6wp at comfortable
7wp at wealthy
8wp at very wealthy
9wp at rich
and 10wp at filthy rich
I can't imagine anyone has so many possessions (and by possessions I don't mean land or property for landbound PC's or ships for seafaring PC's, I mean things like clothing, weapons, armor, animals, etc) that they exceed these numbers. Lei'lira for example, has tons of horses. I looked through her ledger, and according to her ledger her horses altogether value a little more than 3200gn. At very wealthy, she would be given a bonus of +8wp to cover all her belongings (or the 'equivalent' of 8000gn). I think that more than covers it.
So for Faith...
Her wage puts her at rich, which is 196 - 250wp. Each PC starts at the lower end of the wealth tier before adding in their additional wealth (their additional wp value from their savings, property, and possessions). So Faith would have 196wp, but because she's valued at (60000 / 1000 = 60) + the value of her property (value of property / 1000 = ) + 9wp (to account for her possessions) that would actually put her into the filthy rich category at 265+wp (filthy rich is 251 and above). However, as Pegasus suggested, her seasonal pay would remain what it was before (21 or 22wp/season).
For Lei'lira...
Her wage puts her at very wealthy, which is 141 - 195wp. Starting at the lower end of the wealth tier, she would have 141wp, but because she's valued at (111 / 1000 = 0.111 rounded up to 1) + the value of her property (23181 / 1000 = 23.181 rounded up to 24) + 8wp (to account for her possessions), she would start with 141 + 1 + 24 + 8 = 174wp. She would still be considered very wealthy at that wealth point value.
As for determining a player's starting seasonal pay...
They would take their current daily wage and their total value in wp (so for Faith it would be 73gn/day and 265+wp and for Lei'lira it would be 46gn/day and 174wp), and depending on their value use this table

So for Faith her starting seasonal wage would be 22wp/season. For Lei'lira her starting seasonal wage would be 19wp/season.
Note: The examples given (Faith and Lei'lira) are only approximates because I have only a cursory idea of what their total property value etc. are. Faith and Lei'lira would likely still have to go and look through their ledgers / CSs to determine what their exact wealth values would be.
Also note that the additional wealth is broken up into 3 categories, property, savings, and possessions. Property includes land, buildings they own, and things like ships. Savings is how much gn they've accumulated in their ledgers and in banks. Possessions include everything else (animals, equipment, clothing, etc.).
