Is it possible to create a linear network of RF repeaters (Daisy Chain)?

Good day, It is
necessary to create a chain of radio signal repeaters (for example, at 433 Mhz) which will consist of 5-10 elements.
Example scheme :
[Transmitter\Receiver]<---------RF------->[Repeater]<---------RF------->[ Repeater]<---------RF------->[Repeater]<---------RF------->[Transmitter\Receiver] I
assume that the problem lies in the same frequency of operation of all repeaters (Two neighboring repeaters will drown each other out).
What if we take a Transmitter\Receiver module, for example, with 10 channels, and put it throughout the chain instead of a repeater? Like this:
[Transmitter\Receiver]<---------RF(433 Mhz)------->[Transmitter\Receiver<---WIRE--->Transmitter\Receiver]<---- -----RF(433.1 Mhz)------->[Transmitter\Receiver<---WIRE--->Transmitter\Receiver]<---------RF(433.2 Mhz)------->[Transmitter\Receiver]
*Tx on intermediate modules will be wired to Rx and vice versa.
Transmitter \ Receiver like this
In case I'm wrong - is there any way to solve this problem?
Thanks in advance,
Ilya

Why so many?
By the way, you invented a bicycle - an amateur radio repeater with frequency spacing :)

Given the price of those repeaters that you indicated in the question, does it even make sense to pervert like this, it’s easier to hang 1 cheap smart with an android (1500 rubles) and a bluetooth module on each end, it will turn out the same thing only without hemorrhoids. And for "savings" to buy a per-megabyte tariff for 15 years in advance.

And what is the end goal of all this action?
Perhaps I can suggest a better solution than many 433 repeaters.
