Yes, it may be worth it if your into PL'ing or general strength training.. I believe you mean alternate each style lift weekly. Another way is doing (for example) regular DL's on monday and rack DL's on thursday .Quite a few lifters do it that way. I do on occasion. Usually a good idea to keep the form constant when doing floor DL's, at least every week or on a 9 day cycle.
If into only BB'ing, than really no need to do DL's off the floor, but replace that with doing DL's with-in a PR. Having the pins set around knee (or a little bit below) level. No PR, than use heavy designed boxes, adding 2X10's when needed. Some men will have to admit that their body structure will never adapt to the regular DL. And are only inviting injury. DL's are an exceptional movement but not a total requirement for getting a massive traps and back.
Actually I think (personal view only) the SLDL and Romanian versions of DL's is much more adaptable and productive for most BB'ers. And even PL'ers, as a alternate training tool. Also the DL/trap/shrug bar has helped a great many men with the knee and back problems that may develop with a regular straight bar. And with the hands held in a more natural way, thumbs straight ahead. Good Luck.
