We will consider it, but personally I'm not a fan of this idea. I think the Rewards section should contain exact figures only. The pool deals in LTC exclusively, and adding any estimates that depend on (potentially highly volatile) exchange rates may be seen as misleading by some users.
Yes, the rates can be very volatile, I think all miners know and understand this. There is already a recalculation for 1 LTC in the page header, but my power is not equal to that, which is why there is a difficulty with the calculation, so the recalculation in relation to the daily income is very convenient.
The calculator also has a recalculation, but for some reason it does not use Reference Currency, and it is not convenient to substitute your data all the time.
Conversion to BTC/Reference Currency is very important and convenient in my opinion and should be available in a hint or in a separate field next to all values in LTC.
