Deep nested relationship whereHas and with - laravel

Question

I have been stuck on this one for a few days, in part due to the depths of the query. You might as well have the true query in all its current glory too:
$submissions = Submission::with([
'authGroupPriority',
'authGroupPriority.groupData',
'claimData',
'claimData.claimUser',
'claimData.claimForm',
'claimData.claimStatus',
'authGroupPriority.formData',// => function($query){$query->where('forms.id', 1);},
'authGroupPriority.users' => function($query){
$query->where('users.id', Auth::id());
}])->whereHas('authGroupPriority.users', function($query){
$query->where('users.id', Auth::id());
})/*->whereHas('authGroupPriority.formData', function($query){$query->where('forms.id', 1);})*/
->get();
Right so most of the relationships are one to one or one to many relationships here and this is the desired outcome:
Submission
WHERE current user is in list of authGroupPriority.users
WHERE submission.level EQUALS claimData.claimForm.authGroups.level
Thats the basics anyway. I am happy with setting up whereHas and with functions to be the same, just can't work out how to pass in submission level in a whereHas (or with) on the deep nested relationship. Any ideas or am I overcomplicating this somehow?
EDIT:
After spending the afternoon on this query I finally got the one that works (in SQL)
SELECT * from submissions
INNER JOIN(SELECT users.uid, forms.id, forms.name, claims.id AS claimsId FROM claims
INNER JOIN submissions ON submissions.claim = claims.id
INNER JOIN forms ON forms.forms.id = claims.form
INNER JOIN users ON claims.user = users.id) F ON F.claimsId = submissions.claim
INNER JOIN (SELECT auth_group_members.priority FROM auth_group_members
INNER JOIN groupmembership ON auth_group_members.authGroup = groupmembership.groupID
WHERE groupmembership.userID = 1) AG ON AG.priority = submissions.chainPosition
GROUP BY submissions.claim;
Its not pretty but it works. The question is, is this Laravelifiable (new word I think I'm going to claim)? (withs and wherehas's)
EDIT 2:
The SQL above isn't right but its almost right. Just got one more filter to add and thats the submission level = the auth groups level
EDIT 3:
SELECT * FROM submissions
INNER JOIN (SELECT users.uid, forms.id, forms.name, claims.id as claimsId FROM claims
INNER JOIN submissions ON submissions.claim = claims.id
INNER JOIN forms ON forms.forms.id = claims.form
INNER JOIN users ON claims.user = users.id) F ON F.claimsId = submissions.claim
INNER JOIN (SELECT auth_group_members.form, auth_group_members.priority FROM auth_group_members
INNER JOIN groupmembership ON auth_group_members.authGroup = groupmembership.groupID
WHERE groupmembership.userID = 1) AG ON AG.priority = submissions.chainPosition AND AG.form = F.id
GROUP BY submissions.claim
