Munber of slots for mounted Images (MaxMountedImages)

Since TGE 1.3 it seems that the maximum number of mounted objects for a shapeBase was set to 4 (it was 8 before that).
This meens that we can't use slots 4 to 7 for mounting Images, for example this doesn't work:

%player.mountImage(CrownImage,5);

For our game we really need to use more than 4 slots.
I updated "MaxMountedImages" and set it to 8

enum PublicConstants {
      ThreadSequenceBits = 6,
      MaxSequenceIndex = (1 << ThreadSequenceBits) - 1,
      EnergyLevelBits = 5,
      DamageLevelBits = 6,
      DamageStateBits = 2,
      // The thread and image limits should not be changed without
      // also changing the ShapeBaseMasks enum values declared
      // further down.
      MaxSoundThreads =  4,            ///< Should be a power of 2
      MaxScriptThreads = 4,            ///< Should be a power of 2
      [b]MaxMountedImages = 8,//MF old : MaxMountedImages = 4,[/b]            ///< Should be a power of 2
      MaxImageEmitters = 3,
      NumImageBits = 3,
      ShieldNormalBits = 8,
      CollisionTimeoutValue = 250      ///< Timeout in ms.
   };

It compile fine and now I can use the losted slots (note that documentation still state that we can use up to 8 slots).
I understand that it may have consequences on the TGE network, that's why I would like to know if I will need to make some other changes somwhere else in the source code.
Any ideas? Will this update produce bugs related to network? I am fine with just updating this value?
