Could I ask for 5 coats of arms? No supporters necessary, just the shields.

They are for: 1. House of Osman in Exile (descendants of
Cem Sultan) (the chief representing their claims on the Roman Empire (blue used because purple would probably be impractical) while the field representing Turks/Ottoman Empire as a whole); 2. England, as ruled by House of Osman-Tudor (Elizabeth I marrying great-grandson of Cem) (quartered French and "Ottoman" arms since both represent claims); 3. Kingdom of the Netherlands, ruled by House of Osman-Tudor, Edinburgh cadet branch (later also known as Netherlands branch) (the non-Dutch quarters representing the House on dexter and this branch's title as Duke of Edinburgh sinister); 4. United Kingdom of Great Britain, Ireland and the Netherlands (ruled by Osman-Tudor-Edinburgh/Netherlands) (Wales, West Ireland, Flanders and Southern Netherlands (separated from England as OTL, Ireland partitioned between Catholics and Protestants with there being more Protestants than OTL, Both later separated from the Netherlands) not representing like how Wales isn't represented in OTL UK), escutcheon to represent the ruling dynasty (see the Hanoverian CoA of UK); 5. Lesser Coat of Arms (since I am only asking for a shield) of the Rumelian Empire, a dominion (with the OTL branch of the Ottoman dynasty remaining as Caliphs and hereditary Governors-General) (1st quarter representing the house, 2nd quarter representing Bulgaria and the Bulgars, 3rd representing the Turks (Green for Rumelia, Red for Anatolia) and 4th representing Greeks and the Byzantine Empire)
I had posted about this timeline before but I think they might be slightly outdated. Posting the latest World Map because it might help:
It is not meant to be very realistic but I think it is possible but extremely improbable rather than ASB. It is kind of a Brit/Ottoman/Monarchy wank.
