Scotland wasn't conquered it was political union.
The union of the crowns ended up being under the Scottish crown when Elizabeth died childless.
There hasn't been an English parliament since the union, it's been, and still is, a British parliament. There are devolved powers to Scotland, Wales and Northern Ireland but that is about local concerns, national matters are still considered in the national parliment.
The argument you can't have Elizabeth and a British Civ makes as much sense as saying you can't have Washington leading an American Civ, as when Washington was president it didn't include the Republic of Texas.
