Adding a 2nd drain connection in laundry room

The current configuration of our laundry room uses a deep sink that also serves to drain the washer. The deep sink drain line slopes down and attaches to a cast iron T, which is connected to a clean-out right underneath it, with a ventpipe, above. Can I replace the T with a cross, to create an additional connection on the opposite side of the existing T so I can add a washer box and dedicated drain for the washer inside the wall? The existing drain/line line is 2". OR, can I just tie into the vent line above the existing T, with another T? Thanks for your help.

That would work---I try to avoid X fittings on a washer line---the blast of water can cross the x and end up in the sink--

Could you install two T fittings instead?

Here is a picture of the existing piping for the deepsink to the drain. I want to add the washer drain pipe to the right of the T.

If the O.D. of your pipe is 2", then it's actually 1.5" nominal. That means no washing machine install- code wants it on a 2" nominal drain.
