Trying for a straightforward vaginal delivery following a CS, go for it, works for many women, cheering you on.
At home? I'm, really trying not to be brutal here, but no , no, no.
Rupture of the uterus in labour is a very very rare complication - but it does happen.
In hospital, you both stand a chance, as you can be rushed into an operating theatre within minutes.
At home, waiting for an ambulance, which may not be available for some time, loading into ambulance on a stretcher, getting to hospital, unloading, etc etc. You'll be lucky to make it.You owe to the DC you already have not to opt for this.
Go and visit the hospital,. good straightforward hospital birth can be a very different experience from a complicated one; you can request things according to your wishes.
Best wishes, hope all goes well.
