No method on earth is that going to be retrofit possibility for the present R5. What ‘options’ would they’ve for the R5C and R5II?
However on a sensible degree you’ll have to interchange the hotshoe, the highest plate and a load of electronics inside to accommodate an ‘improve’ so there’s completely no method that’s going to occur.
Don’t neglect the introduced TEAC accent could be mounted and used on an R5 already, simply by way of batteries and a cable.
