Practical? Please define practical.
There are a number of good reasons for using a mixer (and a competent operator).
1. They let you vary volumes without shaking the camera or getting in the way of the camera op.
2. You may need to do that a lot with some people. I ride gain even if one person is talking if their voice fades on the end of each line. You can only do this in a relatively quiet environment, otherwise you bring up the ambient noise.
3. Mixer preamps (good ones) sound better than camera preamps.
4. Good mixers have input transformers that scrape off RF before it get into your audio.
5. Good mixers have limiters that allow you to record hotter, keeping your audio further above the noise floor without distorting.
6. Good mixers have EQ that lets you roll of LF HVAC noise before it gets into your audio.
7. Good mixers have mulitple outputs so you can feed more than one camera, or separate recorder simultaneously.
8. Good mixers make your sound better. If they didn’t pros wouldn’t use them.
You don’t mention a competent boom operator. A big budget film team frequently is comprised of three people. A recordist/mixer, a boom op and a utility person. If the mic isn’t pointed the right way, how well you record doesn’t really matter.
Is it an exceptable alternative? (sic) Are you planning to put the camera on sticks, sit auto and have the action happen in front of it with no camera motion?
Back to your question. CAN you do it? Sure. What will you get? Who knows?
Bottom Line: As long as you’re your own client, do anything you want.
