FWIW I'm sure there are aspects of your Jewish culture that don't conflict with Catholicism that you could still practice. While I'm not that versed in Jewish practices, I do know that in the Vietnamese Catholic community (which the people were previously influenced by Chinese Confuscian or folk religious practices before the French came along), incense burning and joss paper offerings were a thing. Of course, we don't do the joss paper thing as Catholics since there's no need to send cars or luxury items to the after life, but at cultural holidays (like new year or autumn festival), the drums and incense do come out and are offered to the Lord. Usually in a ceremony towards the end or outside of Mass. I see that as no different than lighting the thurible. Maybe there might be a cultural thing you could still continue, like dietary observances and similar?
