Does this detail look ok?

I want to simplify the installation of the Radon membrane and if I can do the below, eg run the lower DPC under the inner leaf and across the cavity and then up the inner face of the outer leaf.  If I can go with this approach, it completely negates me having to use pre formed door openings OR having to try and bodge it together.  The only required detailing will be the 4 corners.



The standard Visqueen detailing is shown below, but if you go with this approach, then you have to mess around at door openings.  I just want to avoid as many taped joints as possible.
