I'm afraid it does not work in this way. The following process is more likely to get desired result:

1. Patch authors who own copyright on the code and understand why each piece is needed should contribute patches to codereview.qt-project.org. 

2. When you end up with sane amount of local patches (maybe 3-5) which you cannot handle in a step (1), we can discuss it again.

Revived QtWebKit[1] supports MinGW[2], you can use instead of QtWebEngine for some applications

[1] http://qtwebkit.blogspot.ru/2016/08/qtwebkit-im-back.html
[2]actually, it's in a one patch distance from it, will be fixed soon

> Plus, a lot of work has been done on Qt 5.8.0 in that sense, so probably some things have already been addressed or just need to be lightly adjusted.

> Hi all,
> We need to start preparations for Qt5.9 release even Qt 5.8.0 isn't out yet :) There are some things to be agreed already now:
>
> - Qt 5.9.0 Feature Freeze
> - Changes in supported platforms/configurations
>
> So first of all let's agree the feature freeze date: I propose to have the FF 1.2.2017. From the history we can see that time needed from FF to final release is (even more than) 17 weeks. I know it is too long time but at the moment that is the fact and there is no evidence that we can do it within shorter schedule. We are trying to find ways to make it shorter but at the moment there isn't any big improvements coming and so on that 17 weeks is the best base for our plans. So if we want to get Qt 5.9.0 release out before summer holidays we need to have ff at the beginning of February.
>
> And note: At this time we want to keep the FF date to be able to keep the schedule. That means there won't be any exceptions: If feature isn't ready and in at FF date then it won't be in Qt 5.9 release. So please make sure all new features are in early enough & those are fulfilling the ff requirements: https://wiki.qt.io/Qt_5_Feature_Freeze
>
> Then I propose following changes in supported platforms/configurations:
>
> - We have earlier agreed that for Apple we will support three latest versions. So this means
>    * For macOS we drop 10.9 and support 10.10, 10.11 & 10.12
>    * For iOS we drop 7.x and support 8.x, 9.x, 10.x
>
> - I propose to drop standalone macOS Android installer; One having iOS & Android should be enough
>
> - For MinGW I propose to start delivering 64 bit binary packages instead of 32 bit one & start using MinGW 6.x (6.2?)
>
> - For Windows Android I propose to start doing Android Windows build with MinGW53 (if we are able to build it. Otherwise MinGW49 will be used as with 5.8)
>
> - For WinRT/WinPhone I propose to drop WinRT 8.1 and WinPhone 8.1 support & start using term UWP (Universal Windows platform). It means also dropping msvc 2013 from WinRT/WinPhone; UWP only supports msvc2015
>
> - Start supporting QNX 7.0
