I've not tried but I've entertained the idea.

However, I dropped interest when I realized the effort needed to, first, de-prime or de-cap the Berdan cases and then trying to find the scarce Berdan primers.

For all the added effort I'd rather spend the money and time in obtaining new or gently used Boxer cases.

There have been attempts to manufacture special decapping tools to deal with the two tiny holes associated with Berdan primed cases. There have even been attempts to struggle with hydrolic removal of the primers and with other ideas of primer removal.

There has even been detailed instructions on how to drill out the Berdan primer and to drill a flash hole for use with Boxer primers. However, even the primer pockets are of different diameter when comparing the Berdan primer with the Boxer primer.

To me it's just too big a pain in the butt to work with.
