When it comes to sheer strength training I would have to give the nod to
@Hyde or
@dapack , but things to consider here. Is there a time frame for you hitting your strength goals? If you have a tight time frame you want to hit your goals then slimming up a lot might not be a great idea right now. Specificity is king when it comes to training for a goal. So if you want it and want it now so to speak then stick with the focus.
If you don't have a time frame and would like to lean up and increase general fitness then I think this is a great idea and you can still pop in some triples here and there to keep the CNS up to snuff. Then when you return to strength focus you will be doing it from a nice and lean platform, your connective tissue would probably be well recovered and ready to push. However you probably wouldn't be seeing any hypertrophy with that if cutting just hypertrophy training to minimize muscle loss. There are definitely some benefits to leaning out, then building up strength out of that rebound. However, I don't think doing this gets you to your total goal any faster than just plugging away at it. However you might enjoy the break and being leaner for a bit. Plus it will be good for your health.
I think both are great options, just figure out your motivation for why you are thinking of this change and if it is a worthy of the change for you. If so then go for it. Only real consideration is time frame, and what is the most immediate priority for you.
