It is possible, but theres couple of things that we have to consider.
1) Is the looper passive or active?
2) any possibilities of phase cancellation when you combined the 2 loops and blend into one output.
On 1), with passive looper, when you split the mono signal going into 2 chain of delay in parallel, normally there will be signal loss/volume drop/loss of hi frequency in your guitar signal. Even with clean boost or eqing in the chain, its quite hard to achieve a satisfactory result. Basically the guitar signal will soun dull and dead
to split the guitar signal going into 2 loops of parallel efx with maximum performance, you will need a active mixer circuit, the guitar signal is split and preserve the quality before going into the loop and process by the delay(in this case), combined together and lastly output to amp.
For 2) its less of worries(imho). For guitar effect, usallly the signal when going thru the circuit, they might be some processing where the guitar signal might become in phase or outta phase(kinda like negative cycle or positive cycle of a waveform). When you combined 2 effect in parallel and just "nice" one effect pedal has it output signal outta phase with the another pedal in the other loop, you will have signal cancellation, kinda like -1 plus +1, in the end, you guitar singal might sound hollowish or weak.
In short, if you wanna split signal and combine into one output in parallel effect processing, you will need active mixer(buffered loops) for even result
