Need advice CZ P07 vortex venom red dot sight

[Datooooooo]

Hello,

I own CZ P07 with a threaded barrel,
I attached Olight PL PRO Valkyrie and now planning to install Vortex Venom Red Dot Sight 3 MOA using OuterImpact Red Dot Adapter/Mount.

Need advice, what height should be a front sight to use the white lines on venom to use as a normal when the red dot is off??? 

Standard Front Sight height for P-07/P-09 is – H3 -- 5,75 mm

As I found the options are:
Front Sight with Dot H4 - 6 mm, H5 – 6.25 mm, H7 - 6.75 mm, H8 - 7 mm, Dot H9 - 7.5 mm, H10 - 8 mm
, H11 - 8.5 mm or maybe higher?

Because this adapter plate appears to be a dovetail mount, the optic will sit higher on the slide than it would with a milled slide. Unfortunately, I don't know if there is a front sight tall enough for that.

The tallest front sight I have found is the 12.2mm tall CZ Black (blade width 3.1mm) P-07 P-09 P-10

Might talk to Cajun Gun Works about something custom.
