I think the best thing to do is start working lifting in (which is why I recommended a very low TM) and see how you handle it.
I’m in a similar situation now. I’ve lifted seriously for a little over four years but I"m only 3 months into BJJ. So I’ve put my lifting on the back burner, going down to 1-2 days/week and 2-3 days of rolling per week. My priority is BJJ, and I know I can more or less maintain my strength with 2 days/week of lifting. Plus I’ve learned that a 600 lb deadlift doesn’t really count for too much on the mats, unless I need to move myself and my partner over to open mat space while he’s trying to sink a triangle on me.
As far as recovery goes, you will probably have a rough few weeks if you haven’t been lifting consistently. Once you grow accustomed to lifting, I think 3 days of full body lifting and 3-4 days of rolling is do-able for most guys our age. Yes, even with deadlifts. I’ve rolled the day after squatting 425 on a SSB bar and I was fine by the time we were done with BJJ warm-ups, but I’ve also squatted every week for the last four years. Getting used to lifting takes time and consistency.
The bottom line is this… If you are serious about getting bigger and stronger, you’ll need to do what it takes to get bigger and stronger. Start by fitting the lifting into your life and making sure you are eating for recovery. If you are getting stronger and adding size, well, you’re in the sweet spot. If not, you’ll need to adjust.
