"timer causing lag"...
This can't be serious, right?
Then, build the actual vanilla redstone equivalent for what you need, and come back.
It should be pretty similar lag wise, and is nowhere near as modular.
You might want to limit the use of redwire, and use its insulated versions instead, because if one single RP timer causes you lag spikes, I can bet that way more stuff will when you build more stuff, and automate lots of machines...
