With the use of a decent, proper mount (Chief RPA PJ Specific) at the proper throw distance, the Kids can easily stand within 4'-5' of the screen.
Be advised that the Throw distance you want / need is based upon the distance between the face of the Lens and the screen surface....not the center point of the mount / projector. Also, the W1080ST has a small degree of Image Offset (2" off Len's center) so to create a Screen height of 88" off the floor with the bottom of the screen being 22" off the floor. (..at 135" diagonal and a 66" screen height...) the distance between the Ceiling and the "Center" of the Lens will need to be 6". You do not want to be any closer...the PJ needs breathing space, and you want to avoid the need for using Keystone adjustment. Also, a mount like the Chief RPA is going to help you acheive a rock-steady mounting solution that is going to be ideally suited for the Low profile needs you have.
NO mount such as the Mustang or a Video Secure, or ANY such inexpensive, single mount point affair is going to be workable, let alone acceptable.
You absolutely need to move the electrical / video stubs back to 8' to allow room for the Mount's installation, the cables to be located at the rear of the PJ, and the Lens to wind up at between 7' and 7.5'
And very bluntly put, the w1080st ain't really all that bright...and at 135" diagonal, everything needs to be exactly balanced and as optimally set up as possible.
Two things, you do need to strongly consider Light Silver Milliskin Spandex over White Milliskin, as it has been measured to be excellent AT material, but you should also carry that discussion over to DIY Screens where experience in such matters is both more extensive as well as that forum being a more appropriate venue for such discussions..
