You shave time off dead weeks and sprinkle a few extra sq into regular rewards so that the amount of handouts matches jp despite the slightly condensed timeframe. Over time you gradually catch up.

Blue Archive did this recently, progressing towards a 3month gap between JP and Global. Realtime isn't practical because there's a turnover rate for bulk translation that requires some degree of time buffer. The big benefit of a short delay is that it eliminates the pressure to integrate bugfixes and QoL early, which means you're no longer essentially maintaining 2 separate development environments in parallel.

The major downside is that seasonal events like christmas and summer become out of sync, during the catchup period, but you can 'solve' this by aiming to close the gap down to 1 year and shuffling events during the catchup period so that seasonal events still happen roughly during their designated season.
