Roland MC-808 trying multiple simultaneous time signatures

Question: Is it possible to have multiple different time signature phrases playing at the same time?
Answer: Yes, in a limited way, using the RPS feature. (details in the description below)

I made this vid after being prompted by a good comment/question from @thepatrickrichardson on another of my videos -
Roland MC-808 RPS first explore - altering patch settings
   • Roland MC-808 RPS first explore - alt...  

Here is how I tried it -

Select a new empty pattern.
Select an empty part to record.
Press REC, select [TR-REC], press ENTER to confirm.
Mode changes to TR-REC STANDBY, change the Rec Beat: parameter to the time signature required eg 7/8
Press PLAY and enter the notes to play
Press stop
**remember to SAVE the pattern** if you want to use it!

The new PHRASE is now ready to be registered in one of the RPS SETs

Press and hold RPS button and select the [RPS SET] you want to use
With the RPS button pressed down, select the pad to assign the PHRASE to

Go have fun !

I tried this by making three Patterns, each having only one PART, with the required different time signature.
Then assigned each of these PART phrases to a different RPS pad in the same RPS SET

ie
3/4 phrase from new Pattern 1 assigned to PAD 2,
4/4 phrase from new Pattern 2 assigned to PAD 3,
5/4 phrase from new Pattern 3 assigned to PAD 4.
(the PAD numbers are arbitrary ie choose any PAD, you don't have to choose the same numbers)

Then choose a 4/4 (or other time signature) Pattern, and pressed play.
Next press the RPS button, toggle HOLD if you need it, and select / play the alternate time signature phrases as desired.

Marvel at the musical mayhem of your creation !

Do you have a different way of doing this?
Please let me know !
