Is there a chance to have CronMapper from QUARTZ to SPRING53 ?

Hi guys,
I'd like to have a mapper from QUARTZ format to SPRING53 as I need to support additional L, # for days of the week and L,W day of the month. After creating my custom one and calling .map method I keep getting a problem that "value missing for a#b cron expresion" even it it's already there inside Cron when I call mapper.map() method (from is quartz definition and to is spring53 type inside CronMapper constuctor). Is there a chance to support this feature in upcoming weeks/months?
