I'm a VGC player so you may have to take some of the things I'll say with a grain of salt, but I feel like there should be similarities between VGC and Doubles OU.
Typically when you try to set trick room up, having just dusclops means that the opponent can easily taunt/double into Dusclops slot to pick up KOs. The most reliable way to set trick room up in my opinion is to either have:
1) Fake out + Dusclops
Mons that can accomplish this that also fit under trick room category are Incineroar and Rillaboom, preferably Incineroar because it can also parting shot to switch into your trick room sweeper but Rillaboom accomplishes the same and exerts offensive pressure as well.
2) Redirection + Dusclops
You can do this with Indeedee + Dusclops (you can almost always set trick room up this way, but it tends to be a very passive lead and you can be stalled easily if your opponent leads with dark types) or Amoonguss + Dusclops which threatens to spam spore and provide free switches into your sweepers.
Personally, I'm not fond of having one trick room setter and 5 trick room sweepers. A typical team should have a bit of balance between offense and defense, trick room and non-trick room. I am aware that dynamax is banned in doubles OU and Glastrier just doesn't become that much of a threat in trick room anymore in my opinion.
Vikavolt is a pokemon which I have never really used or seen, but I won't rule it out just yet. It has the levitate ability which could pair interestingly with Stakataka though I would really encourage you to not use assault vest Vikavolt and try something such as life orb Vikavolt to dish out absurd amounts of damage. You'd have to test it, but I believe that it can be swapped for something else.
Hatterene also isn't that viable under trick room without Indeedee, being unable to spam expanding force which is what really makes it extremely powerful.
I believe that you should try and have a fast mode outside of trick room as well as a mode inside of trick room. This allows more flexibility and catch the opponent off guard. Because dynamax is non-existent in doubles OU, I believe that having Landorus + Zapdos as your fast mode is really nice, being able to freely spam earthquake and discharge.
The last slot is really optional but I've enjoyed using Stakataka + Araquanid in VGC so I'll put it here for you as well, feel free to shift that spot around.

Stakataka optimally wants body press so that it can abuse its beast boosts.
