Tony, you state that the strategy plan is well conceived, indicating you think the bunker placements are still relevant, and are not in need of relocation. You indicate that the bunker clusters on the original drawings were perhaps ham-handed and simplified, indicating to me that rather than a cluster of bunkers with interesting capes and bays, along with some turf that separates the clustered Bs, that some version of large singular amoeba style have been in place through the clubs history.
So, I'd ask how much it would cost for you to have some competent sketch artist do some representations of how you believe the bunkers with the architects original drawn intent as you see them on the original plans, might look if restored to that rugged lip, cape and bay style.
Then query the members or powers that be/ users of the facility and see if that is really their preference with the new look.
Going from the more clean, sterile bunker look of one large amoeba, to an intricate and more dicey next shot potential if you ball goes there with some turf between Bs and long grass lips, etc., may be too much change for the users to support.
So, doing everything available in your consultations with the users/powers that be to make them aware of the way the original intent look and play may appear, is the first effort I'd make.
But, if you do end up doing a good restoration to the original intent, even if it was never actually built before, would require one to still make clear the original archie has the attribution, IMO.
