Welcome Kliss. It is awesome to have you.
An underappreciated reason why SLIDERS hasn't made it's way back is at a fundamental level, it is an expensive show to do well. Even with today's CGI. It narrows it's opportunities. You need a lot of locations, and most of these shows are kept at a reasonable budget by not having a lot of locations and having a lot of fixed costs for the "world" they operate in.
If Sam Esmail had wanted to do Sliders instead of Battlestar Gallactica, I am sure we could have had it back. A proven tv guy who carries a lot of weight. But for most, if not all, the cheesiness of the last couple of seasons lowered the brand to the point where the current talented folks in Hollywood are less likely to want to be associated with it. It's obviously not seen as "cool."
And it doesn't really fit as a broadcast net show - it just isn't broad enough. SyFy is a natural home for it, but you have to overcome the expense issues, and you need a very credible tv person behind it with a vision that will help it overcome all of the other projects in that vein coming to SyFy (who has limited resources -- just look at how they had to walk away from going to series with the Tremors/Kevin Bacon project).
So much of the tv business has changed over the last five years... it's certainly made it more complex. Yea, streaming would be a possibiity for it because they can do some larger budget shows but then you'd need the creators/showrunners who are seen as credible in Hollywood to want to do "SLIDERS" rather than "TRAVELERS" or "TIMELESS" or "COUNTERPART" etc etc.
With something like the Peacock network the challenge is, would the amount of viewers SLIDERS bring to it justify the cost? A reunion movie would be $2-3m A series would be $15-$25m (or more) in production costs. There's still somewhat good brand awareness of what sliders is for folks 35+ to say 55 who might care but it's just not big enough to really support those costs on name alone. So you'd need to start fresh (story wise), with an incredible vision, and a respected tv showrunner to believe, yes, this could earn it's money back. And then that goes back to the brand issues again, where the people who could produce that would rather do their own thing. Not to mention, if you aren't just using the original story premise/format/characters, it really becomes it's own thing, different enough from SLIDERS where even with the awareness of that brand, it's not necessarily worth it to put a story in that "package" and box it in like that.
