Completely change Advanced HeroQuest by changing the Dungeon and Monster Matrices

Advanced HeroQuest is often described as being very hard on the heroes, so an adjustable level of difficulty might help. Easy mode would simply be using a D10 instead of a D12 on the Lairs/Quest/Wandering Monsters matrices. With a D12, you could reroll anything over 10 to make it easier, or reroll anything under 2 for a harder game.
This works because higher numbers give you more monsters.

In the AHQ Map Generator program, you edit skaven.tab in Notepad.

You can edit this:
Lairs-Matrix
(   1D12
    1-1     "4 Skaven Warriors (40 Gold Crowns)"
    2-2     "2 Skaven Warriors, 1 Champion (40 Gold Crowns)"
    3-3     "5 Skaven Warriors (50 Gold Crowns)"
    4-4     "3 Skaven Warriors, 1 Sentry (50 Gold Crowns)"
    5-5     "6 Skaven Warriors (60 Gold Crowns)"
    6-6     "4 Skaven Warriors, 1 Skaven Champion (60 Gold Crowns)"
    7-7     "2 Skaven Warriors, 2 Skaven Champions (60 Gold Crowns)"
    8-8     "1 Skaven Warlord (60 Gold Crowns)"
    9-9     "6 Skaven Warriors, 1 Skaven Champion (80 Gold Crowns)" & Specialist-Skaven()
    10-10   "6 Skaven Warriors, 1 Skaven Champion (80 Gold Crowns)" & Specialist-Skaven()
    11-11   "2 Skaven Warriors, 1 Skaven Warlord (80 Gold Crowns)" & Specialist-Skaven()
    12-12   "4 Skaven Warriors, 1 Skaven Sentry, 2 Skaven Champions (100 Gold Crowns)" & Specialist-Skaven()
)

To this, to make it easier:
Lairs-Matrix
(   1D12
    1-1     "4 Skaven Warriors (40 Gold Crowns)"
    2-2     "2 Skaven Warriors, 1 Champion (40 Gold Crowns)"
    3-3     "5 Skaven Warriors (50 Gold Crowns)"
    4-4     "3 Skaven Warriors, 1 Sentry (50 Gold Crowns)"
    5-5     "6 Skaven Warriors (60 Gold Crowns)"
    6-6     "4 Skaven Warriors, 1 Skaven Champion (60 Gold Crowns)"
    7-7     "2 Skaven Warriors, 2 Skaven Champions (60 Gold Crowns)"
    8-8     "1 Skaven Warlord (60 Gold Crowns)"
    9-9     "6 Skaven Warriors, 1 Skaven Champion (80 Gold Crowns)" & Specialist-Skaven()
    10-10   "6 Skaven Warriors, 1 Skaven Champion (80 Gold Crowns)" & Specialist-Skaven()
    11-11   "4 Skaven Warriors (40 Gold Crowns)"
    12-12   "2 Skaven Warriors, 1 Champion (40 Gold Crowns)"
) 

You can also change the proportion of empty corridors by editing the "Passage-Feature" matrix in room.tab. You can increase the chance of a Quest Room in the "Room-Type" in the room. You can have more secret doors, more stairs out, and so on.
