Change bits type to gauge?

[llamafilm]

I have a MIB from a Barco cinema projector that defines a bits type with 2 possible values. The snmp exporter shows it like this:

lampMode{lampMode="cloON"} 1
lampMode{lampMode="unused"} 0

Is it possible to override this so it appears as a gauge instead with values either 0 or 7? I would prefer to reduce the number of time series. I tried type: gauge override but that didn't work, that set the value to 0 when it should be 7.

The MIB definition looks like this:

-- 1.3.6.1.4.1.12612.220.11.2.2.4.4
lampMode	OBJECT-TYPE
	SYNTAX BITS
		{
			unused(0),
			cloON(7)
		}
	MAX-ACCESS	read-only
	STATUS	current
	DESCRIPTION
		"This is the lamp mode.
		cloON: Constant Light Output active"
	::= { lampProperties 4 }
